8. Two blocks rest on a horizontal frictionless surface as shown. The surface between the top and bottom blocks is roughened so that there is no slipping between the two blocks. A 30-N force is applied to the bottom block as suggested in the figure A. What is the magnitude of the acceleration of the "two block" system? B. What is the magnitude of the force of static friction between the top and bottom blocks?

Step 1
The total mass is the sum of the masses of the two blocks, which is 5 kg + 10 kg = 15 kg. Show more…

The two blocks $(m=16$ $\mathrm{kg}$ and $M=88 \mathrm{~kg}$ ) in Fig. $6-38$ are not attached to each other. The coefficient of static friction between the blocks is $\mu_{5}=0.38$, but the surface $\mathrm{Fr}$ beneath the larger block is frictionless. What is the minimum magnitude of the horizontal force $\vec{F}$ required to keep the smaller block from slipping down
Two blocks $A$ and $B$ of masses $10 \mathrm{~kg}$ and $15 \mathrm{~kg}$ are placed in contact with each other rest on a rough horizontal surface as shown in the figure. The coefficient of friction between the blocks and surface is $0.2$. A horizontal force of $200 \mathrm{~N}$ is applied to block A. The acceleration of the system is (Take $\left.g=10 \mathrm{~m} \mathrm{~s}^{-2}\right)$ (a) $4 \mathrm{~m} \mathrm{~s}^{-2}$ (b) $6 \mathrm{~m} \mathrm{~s}^{-2}$ (c) $8 \mathrm{~m} \mathrm{~s}^{-2}$ (d) $10 \mathrm{~m} \mathrm{~s}^{-2}$
The two blocks $(m=16$ kg and $M=88 \mathrm{kg}$ ) in Fig. $6-38$ are not attached to each other. The coefficient of static friction between the blocks is $\mu_{s}=0.38,$ but the surface beneath the larger block is frictionless. What is the minimum magnitude of the horizontal force $\vec{F}$ required to keep the smaller block from slipping down the larger block?
